Agricultural terraces

Also known as: Terracing, Stepped fields

Constructed level (or near-level) planting surfaces cut into a sloping landscape, typically held in place by stone, earth, or vegetated walls. Terraces transform steep land — otherwise unsuited to agriculture — into productive farming surfaces while preventing erosion. The Andean cultures of South America, Filipino Banaue rice terraces, Chinese Loess Plateau terraces, Mediterranean olive and grape terraces, and Southeast Asian rice terraces are among the most ecologically and culturally significant terraced landscapes on Earth — many continuously cultivated for 2,000+ years.

Forms

  • Bench terraces — flat planting surfaces with steep walls between; the classical form
  • Sloping terraces — slight inclination across the planting surface; reduces wall height
  • Hillside ditches with cropped strips — minimal-construction form
  • Stone-walled terraces — Mediterranean, Andean tradition; long-lasting infrastructure
  • Earth-walled terraces — common in Asia; vegetated grass walls
  • Rice paddies on terraces — water-holding flooded rice paddies stepped down a slope (Philippines, China, Vietnam)

Famous terraced landscapes

  • Banaue rice terraces (Philippines) — Ifugao Indigenous terraces, 2,000+ years old; UNESCO World Heritage; “Eighth Wonder of the World”
  • Andean terraces (Peru, Bolivia, Ecuador) — Inca and pre-Inca; thousands of years of continuous use; over 1 million hectares of pre-Columbian terraces still partially functional
  • Chinese Loess Plateau — extensive terraces transforming previously eroded landscape; major restoration work since the 1990s
  • Hani rice terraces (Yunnan, China) — UNESCO World Heritage; integrated forest-village-terrace-river system
  • Cinque Terre (Italy) — Mediterranean grape and olive terraces; 1,000+ year continuous cultivation
  • Douro Valley (Portugal) — port wine terraces along the Douro
  • Subak (Bali) — water-temple-coordinated rice terraces; UNESCO

Why terraces matter

  • Soil retention — steep slopes that would lose soil rapidly hold soil for centuries on terraces
  • Water management — terraces capture rainfall; reduce flood downstream, recharge groundwater
  • Land use intensification — land otherwise unsuitable for agriculture becomes productive
  • Carbon storage — well-managed terraced landscapes can store substantial soil carbon over centuries
  • Cultural and ecological landscapes — many terraced landscapes are inseparable from their cultures; UNESCO recognition reflects this

Loss and restoration

Agricultural terraces are vulnerable to abandonment when economics shift away from manual hill agriculture. Mediterranean and Asian terraces have been lost in significant amounts through the 20th century. Restoration projects in Italy, Portugal, Spain, and elsewhere are working to recover terraced landscapes for food production and cultural preservation.
